Controllers used in CompoundJS. Could be used separately. This package provides
efficient way of describing controllers, it works insanely fast (sometimes
even faster then manually written express controller). Optimized for high
performance.

Controllers produced via kontroller designed to be fast as possible. Every
controller instance could be reused multiple times (to save time for it's
instantiation and reduce memory usage). This trick allows to save same
performance level as it would be for just function, and not separate object

The only problem here in concurrent requests. Obviously, concurrent requests
should be handled using different controller instances, so we have pool for
controllers. When request comes, firts of all we trying to pull controller from
the pool, and only if pool is empty - creating new instance. After request
handling is completed - controller instance pushed back to pool.
